Zeroes not going into date input field

This is really weird. Anybody have a clue why this is happening? Could this be a firefox beta thing?

I tested this on MDN, and switching to insert mode fixes it. The mode does automatically change to insert on the initial focus, but then it switches back to normal when focusing the next part. Manually switching to insert mode on each part makes it work as expected. https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/input/date
